#彗星# 60度尾巴

Details:



I finally imaged comet Leonard with a wide angle lens in order to find out the real extension of the tail. Good news: I finally managed to keep it entirely on the FOV. The tail is extended about 60 degree: impressive! This image has been taken with a 28 mm f2.8 lens and Sony A7s full frame camera. The image has not been cropped. It is the average of 131 exposures of 30 seconds. I superimposed the background of the last image of the sequence in order to have a better idea of the proportions of the tail.
